2017 pathfinder misfiring
I have V6, 3.5L 2017 Nissan Pathfinder with 20K miles on it. All 6 cylinders have misfiring. Some more, some less. The computer is not throwing any codes, and it was a challenge to detect this in the first place. I had to have a technician sitting next to me with a computer hooked up to the car to be able to see pistons misfiring. Car's been in the shop for over 3 weeks, and they cannot figure out what is causing the misfire. Any advise?
